IMPROVEMENT m FARMERS'BOILERS.

The Schedule referred to in these Letters Patent and making part oithe same.

To all whom. this may concern s Be it known that I, JOSEPH H. HUXTER, of Pennington Point, in the county of McDonongh and State of Illinois, have invented a new and useful Improvement in Farmers Boilers; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawing and letters marked thereonmuking apart of this specification, in which- Figure l is a. plan view of my improved boiler, wit-h the lid open. Figure 2, a longitudinal sectional elevation of the same.

Figure 3, a transverse section; I

The object of the present invent-ion isto provide "more convenient means for boilingor -steaming feed for stock; and I A The nature is more clearly set forthas follows:

A represents an outer tank, which has its sides and ends made of wood, to the bottom of which is securely fastened a metal plate, M, resting over a suitable furnace or fire-box, 0.

The top of the tank is provided with a cover or lid, 13 I, and to the middle part of the insideis fixed strips or bearings for the support of an inner tank, 0, there being suiiic-ient space between the bot-tom of the inner.

tank and the bottom of the outer one to hold -a suitable supply of water for generating steam, as shown of the said 'innertank is placed a semicircular plate,

D, which is perforatedwith holes and used to convey steam to the central part ofthe feed, so that it may be all cooked alike.

The steam is conveyed to the part D by means of a box-pipe, K, which extends through the bottom of tank and communicates with the steam and water- 'chamber below the said tank, as shown at fig. 2.

The object of making the part D in the form of an inverted trough is that it may not fill up and prevent steam from penetrating the middle part of the feed, as is the case when such parts of the boiler have cylindrical forms. It, in the, present construction, any

feed falls through the holes in the part D, it will pass out of itas soon as the inner tank is emptied.

At the end of the inner and the outer tanks is a space, in which is placed a float, E G, by means of which the height of water in the bottom of the outer tank is shown, said float rising and falling with the water in the usual manner of'such devices.

. The lid or cover of the outer tank is provided-with holes, F, and covered with some flexible substance, R, to allow a free escape of steam.

The water is drawn oil by means of a stop-cock at b.

. Having thus described my invention,

\Vhatl claim, and desire by Letters Patent, is The combination of the outer and inner tanks A O, water-indicator E G, strips L J, and steam-conductors, K I), constructedaml arranged as set forth.

JOSEPH H. HUNTER.
